Mat Board

The composition of the type of matboard you use is of concern if the art you are matting is original or valuable. For these types of matting jobs, you will want to invest in quality board made of 100% cotton rag fibers or purified lignin-free wood pulp treated with an alkaline buffer to absorb atmospheric acidity. These matboards are usually called "museum quality ", "archival" or "acid-free ".
